03.08.1999· Critical rotation speed of dry ball-mill was studied by experiments and by numerical simulation using Discrete Element Method (DEM). The results carried out by both methods showed good agreement. It has been commonly accepted that the critical rotation speed is a function of a ball radius and a jar diameter. The results of the present work, however, show that the critical rotation speed
